Tnikit,
I have to petitions:
1) Can you post where can you get that free material or at least the ones you like the most. There are so many places that really sometimes i get lost.
2) What is mastermind. Do you mean the game wher you have to guess the colors and positions? I use to play that when i was young and also with pen and paper at school. Just now i saw in amazon one version for kids:
